A hollow cylinder inserted orally or nasally into the trachea to provide an unobstructed airway to convey gases and vapours to and from the lungs during anaesthesia, resuscitation, and other situations where the patient is not properly ventilated. The device may: 1) be packaged with a connector that will attach to a breathing circuit or manual resuscitator; 2) have a distal inflatable cuff to seal against the tracheal wall; 3) be radiopaque; and 4) have a built-in pilot balloon for cuff pressure monitoring. It is typically made of plastic or rubber and is available in various diameters and lengths for adult and paediatric patients. This is a single-use device.
